GENERAL DESCRIPTION

The CUB5T provides the ultimate in timer flexibility, from its complete user
programming to the optional relay output and serial communications capability.
The meter functions as an Elapsed Timer or Preset Timer. It also has a built-in
Cycle Counter. The display can be toggled either manually or automatically
between the Timer and Cycle Counter values. With eight different input
operating modes and 18 selectable timer ranges, the meter can be programmed
for a wide variety of timing applications.

The CUB5T has an LCD display with 0.46" (11.7 mm) high digits. The LCD
is available in two versions, reflective (CUB5TR00) and backlight (CUB5TB00).
The backlight version is user selectable for red or green backlighting with
variable display intensity.

The Timer has two signal inputs and eight input operating modes. These
modes provide level active or edge triggered start/stop operation. A Display
Hold mode will display the elapsed time for one cycle, while the next cycle
continues timing internally. The Timer Reset modes will automatically reset the
timer value when a time start edge is applied to the input. This allows sequential
timing cycles without having to manually reset the Timer.

In addition to the Timer inputs, a programmable User Input is available to
perform a variety of meter functions. All inputs are current sinking (active low)
and accept a variety of logic and open-collector output signal sources. Relay and
switch contacts can also be used as signal sources, when the software input
debounce filter is enabled.

The capability of the CUB5T can be easily expanded with the addition of a
field installable option module. When the CUB5RLY0 relay output module is
added, the meter becomes a Preset Timer. The Setpoint Output can be assigned
to the Timer or Cycle Counter values, and configured to suit a variety of control
and alarm requirements. Serial communications capability for RS232 or RS485
is added with a serial option module (CUB5COM).

The CUB5T can be powered from an optional Red Lion Micro-Line/Sensor
Power Supply (MLPS), which attaches directly to the back of a CUB5T. The
MLPS is powered from an 85 to 250 VAC source and provides up to 400 mA to
drive the meter and sensors.

3.0 INSTALLING PLUG-IN CARDS

ECEON

4132

The Plug-in cards are separately purchased option cards that perform specific
functions. The cards plug into the main circuit board of the meter after the rear
cover is removed

WARNING: Disconnect all power to the meter before

installing Plug-in Card.

REMOVING THE REAR COVER

To remove the rear cover, locate the cover locking tab below the 2nd and 3rd
input terminals. T o release the tab, insert a small, flat blade screwdriver between
the tab and the plastic wall below the terminals. Inserting the screwdriver will
provide enough pressure to release the tab locks. To replace the cover, align the
cover with the input terminals and press down until the cover snaps into place.

4.0 WIRING THE METER

WIRING OVERVIEW

Electrical connections are made via screw-clamp terminals located on the
back of the meter. All conductors should conform to the meter ’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.

Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed
(stranded wires should be tinned with solder.) Insert the lead under the correct
screw-clamp terminal and tighten until the wire is secure. (Pull wire to verify
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm).

Comms Card

Locking Tab

CAUTION: The Plug-in cards and main circuit board contain static

sensitive components. Before handling the cards, discharge static
charges from your body by touching a grounded bare metal object.
Ideally, handle the cards at a static controlled clean workstation. Also,
only handle the cards by the edges. Dirt, oil or other contaminants
that may contact the cards can adversely affect circuit operation.

EMC INSTALLATION GUIDELINES

Although this meter is designed with a high degree of immunity to Electro­Magnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or coupling method into the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.

1. The meter should be mounted in a metal enclosure, which is properly

connected to protective earth.

2. Use shielded (screened) cables for all Signal and Control inputs. The shield

(screen) pigtail connection should be made as short as possible. The

connection point for the shield depends somewhat upon the application.

Listed below are the recommended methods of connecting the shield, in order

of their effectiveness.

a. Connect the shield only at the panel where the unit is mounted to earth

ground (protective earth).

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is above 1 MHz.

c. Connect the shield to common of the meter and leave the other end of the

shield unconnected and insulated from earth ground.

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be ran in metal conduit that is properly

grounded. This is especially useful in applications where cable runs are long

and portable two-way radios are used in close proximity or if the installation

is near a commercial radio transmitter.

4. Signal or Control cables within an enclosure should be routed as far as possible

from contactors, control relays, transformers, and other noisy components.

5. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional protection.
Install line filters on the power input cable to the unit to suppress power line
interference. Install them near the power entry point of the enclosure. The
following EMI suppression devices (or equivalent) are recommended:

Ferrite Suppression Cores for signal and control cables:

Fair-Rite # 0443167251 (RLC# FCOR0000)
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0

Line Filters for input power cables:

Schaffner # FN610-1/07 (RLC# LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3

Note: Reference manufacturer’s instructions when installing a line filter.

6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.

7. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.

Snubber: RLC# SNUB0000.

Sending Serial Commands and Data

When sending commands to the meter, a string containing at least one
command character must be constructed. A command string consists of a
command character, a value identifier, numerical data (if writing data to the
meter) followed by a command terminator character, * or $.

Command String Construction

The command string must be constructed in a specific sequence. The meter
does not respond with an error message to illegal commands. The following
procedure details construction of a command string:

1. The first 2 or 3 characters consist of the Node Address Specifier (N) followed

by a 1 or 2 character node address number. The node address number of the

meter is programmable. If the node address is 0, this command and the node

address itself may be omitted. This is the only command that may be used in

conjunction with other commands.

2. After the optional address specifier, the next character is the command

character.

3. The next character is the register ID. This identifies the register that the

command affects. The P command does not require a register ID character. It

prints all the active selections chosen in the Print Options menu parameter.

4. If constructing a value change command (writing data), the numeric data is

sent next.

5. All command strings must be terminated with the string termination

characters * or $. The meter does not begin processing the command string

until this character is received. See timing diagram figure for differences in

meter response time when using the * and $ terminating characters.

Address a specific meter. Must be followed by
one or two digit node address. Not required
when node address = 0.

Read a register from the meter. Must be
followed by a register ID character.

Write to register of the meter. Must be
followed by a register ID character and
numeric data.

Reset a value or the output. Must be followed
by a register ID character

3. Node address = 0, Reset Setpoint output
String: RF*

4. Node address = 31, Request a Block Print Output, response time of 2 msec min
String: N31P$

Transmitting Data to the Meter

Numeric data sent to the meter must be limited to Transmit Details listed in the
Register Identification Chart. Leading zeros are ignored. The meter ignores any
decimal point and conforms the number to the appropriate display format. (For
example: The Timer range is set for tenths of a second and 25 is written to the
Timer Start register. The value of the register is now 2.5 seconds. In this case,
write a value of 250 to equal 25.0 seconds).

Note: Since the meter does not issue a reply to value change commands, follow

with a transmit value command for readback verification.

Receiving Data From The Meter

Data is transmitted from the meter in response to either a transmit command
(T), a block print request command (P) or a User Input print request. The
response from the meter is either a full field transmission or an abbreviated
transmission, depending on the selection chosen in Module 5.

20 <LF> (line feed)
21 <SP>* (Space)
22 <CR>* (carriage return)
23 <LF>* (line feed)

* These characters only appear in the last line of a block print.

The first two characters transmitted are the meter address. If the address
assigned is 0, two spaces are substituted. A space follows the meter address field.
The next three characters are the register mnemonic, as shown in the Register
Identification Chart.

The numeric data is transmitted next. The numeric field (bytes 7 to 18) is 12
characters long. When a display overflow exists for a requested timer or cycle
counter value, an * (used as an overflow character) replaces a space in byte 7.
Byte 8 is always a space.

The remaining ten positions of this field consist of seven positions for the
requested value with decimal points positioned for the selected timer range. The

data within bytes 9 to 18 is right-aligned with leading spaces for any unfilled
positions.

The end of the response string is terminated with a <CR> and <LF>. After the
last line of a block print, an extra <SP>, <CR> and <LF> are added to provide
separation between the print blocks.

RESPONSE FROM METER

The meter can only receive data or transmit data at any one time (half-duplex
operation). During RS232 transmissions, the meter ignores commands while
transmitting data, but instead uses RXD as a busy signal. When sending
commands and data to the meter, a delay must be imposed before sending
another command. This allows enough time for the meter to process the
command and prepare for the next command.

At the start of the time interval t
string to the com port, thus initiating a transmission. During t1, the command
characters are under transmission and at the end of this period, the command
terminating character (* or $) is received by the meter. The time duration of t1
is dependent on the number of characters and baud rate of the channel.

t

= (10 times the # of characters) / baud rate

At the start of time interval t2, the meter starts the interpretation of the
command and when complete, performs the command function. This time

varies. If no response from the meter is expected, the meter is ready

2

If the meter is to reply with data, the time interval t2 is controlled by the use
of the command terminating character. The ‘*’ terminating character results in
a response time of 50 msec. minimum. This allows sufficient time for the
release of the sending driver on the RS485 bus. Terminating the command line
with ‘$’ results in a response time (t2) of 2 msec. minimum. The faster response
time of this terminating character requires that sending drivers release within 2
msec. after the terminating character is received.

Communication Format

Data is transferred from the meter through a serial communication channel.
In serial communications, the voltage is switched between a high and low level
at a predetermined rate (baud rate) using ASCII encoding. The receiving device
reads the voltage levels at the same intervals and then translates the switched
levels back to a character. The voltage level conventions depend on the interface
standard. The table lists the voltage levels for each standard.

). Each ASCII character is “framed” with a beginning start bit,

Start Bit and Data Bits

Data transmission always begins with the start bit. The start bit signals the
receiving device to prepare for reception of data. One bit period later, the least
significant bit of the ASCII encoded character is transmitted, followed by the
remaining data bits. The receiving device then reads each bit position as they are
transmitted.

Parity Bit

After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission
(including the parity bit) is either even or odd. This bit is used by the receiver
to detect errors that may occur to an odd number of bits in the transmission.
However, a single parity bit cannot detect errors that may occur to an even
number of bits. Given this limitation, the parity bit is often ignored by the
receiving device. The CUB5T meter ignores the parity bit of incoming data and
sets the parity bit to odd, even or none (mark parity) for outgoing data.

Stop Bit

The last character transmitted is the stop bit. The stop bit provides a single bit
period pause to allow the receiver to prepare to re-synchronize to the start of a
new transmission (start bit of next byte). The receiver then continuously looks
for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2
stop bits are sent from the meter.
